However, we know that there is an ever increasing segment of the present day population that, for whatever reason or reasons, prefer the Latin Mass. Is this because they understand Latin or are they, too, attending a mass that they do not understand? That would make no sense. Yet look at how tenaciously they adhere to it. Can someone iron this out for me?
I think that one needs to have perspective, and what is too often lacking is an overall perspective.
According to a group that tracks the Latin Mass throughout the world, out of approximately 117,000 parishes world wide, about one in 250 have the Latin Mass. That works out to slightly more than 2 tenths of one percent.
There are a number of problems trying to sort out who likes the EF, who wants the EF, how many people are responding positively to it, and variations on that theme.
The first is that there are very few priests trained to say the EF - the rubrics are not as simple as in the OF, and most younger priests are not fluent in Latin; they may have little or no exposure to it.
In addition, there has been no working out what a “stable group” means; so you could have a group of 50 to 100 people in a parish to 1200 families who want the Mass; but no one to say what that effectively means.
Anyone much under the age of 45 has little or no exposure the the EF; so when they express interest in it, it is hard to say to what degree that interest exists. Curiosity? Strong curiosity? Some level of committment to support it? Then, in addition, there is the issue of to what degree the bishop backs the idea; he can be strongly against it, somewhat against it, neutral toward it, in favor or strongly in favor; and add that to the limited number of priests who are trained or interested in being trained, and the question grows stronger.
The short of it is that it is hard to say that the EF will grow much more than it has. For example, Cardinal George of Chicago is not one I would call a liberal. There are 12 (as of the last count I have heard) parishes in the archdiocese which have the EF. That sounds like a lot until you do a nose count; it is something like about 3.5% of the parishes.
There are people who are very enthusiastic about the EF. Some of that is a hunger for stability and reverence; however, where reverence in the OF increases, what will counter growth of the EF is that many people much prefer the vernacular.
I would expect that the EF will continue to grow in availability over time, as we have recalcitrant bishops die or retire, and as we continue to ordain priests who no longer have the issues and ideology of two generations back. But as the Pope said in his accompanying letter, I would not expect perhaps much more than what we currently see, say, in Chicago. History may prove otherwise, but wwe all won’t know until it has occured.
